introduce

Defoamer refers to the evaporation operation, entrainment of a large amount of liquid in the secondary steam, although separated in the separation chamber, but in order to prevent the loss of useful products or pollution of condensed liquid, also need to try to reduce the entrainment of liquid foam, so set in the steam outlet near the defoamer device There are many forms of defoaming device. The most commonly used form can be installed directly on the top of the evaporator, and the less commonly used form is installed outside the evaporator

use

Voice defoamer is used to separate the droplets entrained by gas in the tower to ensure mass transfer efficiency, reduce valuable material loss and improve the operation of the compressor after the tower, reduce water content and prolong the life of the compressor. Generally, the defoamer is set on the top of the tower Can effectively remove 3- 5um fog droplets, if set between the tray, not only can ensure the mass transfer efficiency of the tray, but also can reduce the plate spacing, so the screen defromer is mainly used for gas-liquid separation can also be used for gas separation in the air filter

working principle

When with entrainment gas at a certain speed rise through the screen, due to the effect of inertia of the entrainment rise, entrainment and silk filaments collision was attached on the surface of the filaments filaments on the surface of the spread of the entrainment of entrainment gravity settling, the entrainment form a larger droplets along the two root silk filaments to hand over Filaments of wettability The surface tension of the liquid and capillary action of the filament, making the droplet more and more large, until the droplet gathered to its own gravity exceeds the lifting force of the gas and liquid surface tension of the resultant force, droplet separated from the wire falling gas through the screen defoaming device, basically does not contain fog foam Separation in the gas entrainment, in order to improve the operating conditions, the optimization of process index, reduce the equipment corrosion, prolong the service life of equipment, increase the capacity and recovery of valuable materials, protect the environment, reduce atmosphere pollution and so on simple structure small volume, high defoaming efficiency, small resistance, light weight, easy installation and operation and maintenance, silk screen defoaming of particle size 3~5um foam, the capture efficiency of 98%-99.8%, and the gas through the defoamer pressure drop is very small, only 250-500Pa, is conducive to improving the production efficiency of the equipment
